图片写入文件夹

private static void copy(File src, File dst) {try {    InputStream in = null;    OutputStream out = null;    try {in = new BufferedInputStream(new FileInputStream(src), BUFFER_SIZE);out = new BufferedOutputStream(new FileOutputStream(dst), BUFFER_SIZE);byte[] buffer = new byte[BUFFER_SIZE];while (in.read(buffer) > 0) {    out.write(buffer);}    } finally {if (null != in) {    in.close();}if (null != out) {    out.close();}    }} catch (Exception e) {    e.printStackTrace();}    }

调用：

if (myFile != null && myFile.size() > 0) {

File imageFile1 = new File(ServletActionContext.getServletContext().getRealPath("images") + "/" + "t01.jpg");


if (myFile.get(0) != null) {
copy(myFile.get(0), imageFile1);
}
}
